But this week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby. ![]() This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. For example, scientists note a haze layer about 3 miles (5 kilometers) above the surface (lower left area of the image), which descends to the surface at the right.

NASA’s New Horizons spacecraft continues to make fascinating discoveries about PlutoWritten by Dwayne Brown / Laurie Cantillo
“The New Horizons mission has taken what we thought we knew about Pluto and turned it upside down,” said Jim Green, director of planetary science at NASA Headquarters in Washington. “It’s why we explore — to satisfy our innate curiosity and answer deeper questions about how we got here and what lies beyond the next horizon.” ![]() Locations of more than 1,000 craters mapped on Pluto by NASA’s New Horizons mission indicate a wide range of surface ages, which likely means Pluto has been geologically active throughout its history.

NASA’s New Horizons spacecraft nabs photo of Pluto’s Smallest Moon StyxNASA Headquarters
The Styx images downlinked on October 5th, 2015, were taken by the Long Range Reconnaissance Imager (LORRI) on July 13th, approximately 12.5 hours before New Horizons’ closest approach to Pluto. ![]() This Long Range Reconnaissance Imager (LORRI) composite image of Pluto’s smallest moon, Styx, was taken July 14, 2015, when the New Horizons spacecraft was 391,000 miles (631,000 kilometers) from the tiny moon. The image reveals a highly-elongated satellite, roughly 4.5 miles [7 kilometers] across in its longest dimension and 3 miles [5 kilometers] in its shortest dimension. For context, the orbits of Pluto’s moons are shown above. (NASA/JHUAPL/SwRI) Sections: Technology | No Comments
NASA’s New Horizons Spacecraft sends back first images of Pluto and it’s moon CharonWritten by Dwayne Brown / Laurie Cantillo
“Pluto New Horizons is a true mission of exploration showing us why basic scientific research is so important,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington. “The mission has had nine years to build expectations about what we would see during closest approach to Pluto and Charon. Today, we get the first sampling of the scientific treasure collected during those critical moments, and I can tell you it dramatically surpasses those high expectations.” ![]() New close-up images of a region near Pluto’s equator reveal a giant surprise — a range of youthful mountains rising as high as 11,000 feet (3,500 meters) above the surface of the icy body.

NASA’s New Horizons spacecraft answers decade old question, What is the Size of Pluto?NASA Headquarters
Mission scientists have found Pluto to be 1,473 miles (2,370 kilometers) in diameter, somewhat larger than many prior estimates. Images acquired with the Long Range Reconnaissance Imager (LORRI) were used to make this determination. This result confirms what was already suspected: Pluto is larger than all other known solar system objects beyond the orbit of Neptune. ![]() A portrait from the final approach. Pluto and Charon display striking color and brightness contrast in this composite image from July 11, showing high-resolution black-and-white LORRI images colorized with Ralph data collected from the last rotation of Pluto. Color data being returned by the spacecraft now will update these images, bringing color contrast into sharper focus.

NASA’s New Horizons Spacecraft to be assisted by other missions during Pluto flybyWritten by Whitney Clavin
It won’t be making observations alone; NASA’s fleet of observatories will be busy gathering data before and after to help piece together what we know about Pluto, and what features New Horizons data might help explain. ![]() Artist conception of New Horizons Spacecraft.

NASA’s Hubble Space Telescope reveals chaotic wobbling dance of Pluto’s Moons Nix and HydraWritten by Felicia Chou
“Hubble has provided a new view of Pluto and its moons revealing a cosmic dance with a chaotic rhythm,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate in Washington. “When the New Horizons spacecraft flies through the Pluto system in July we’ll get a chance to see what these moons look like up close and personal.” ![]() This illustration shows the scale and comparative brightness of Pluto’s small satellites. The surface craters are for illustration only and do not represent real imaging data. (NASA/ESA/A. Feild (STScI)) «Read the rest of this article» Sections: Technology | No Comments
NASA’s New Horizons spacecraft takes images of small Moons Orbiting PlutoNASA’s Science Mission Directorate
The moons Nix and Hydra are visible in a series of images taken by the New Horizons spacecraft from January 27th-February 8th, at distances ranging from about 125 million to 115 million miles (201 million to 186 million kilometers). The long-exposure images offer New Horizons’ best view yet of these two small moons circling Pluto which Tombaugh discovered at Lowell Observatory in Flagstaff, Arizona, on February 18th, 1930. ![]() The moons Nix and Hydra are visible in a series of images taken by the New Horizons spacecraft.
